    I have gone to the Dell site and looked up the maximum amount of memory
    that can be inserted in a Dimension 8400, Dell says 2GB max, but I have
    seen sites that sell memory ( corsair ) that state a Dimension 8400 can
    have as much as 4GB. Does anyone know what the correct amount is?

    Even if you put 4GB of memory in the computer, Windows won't see all of it:
    some of the memory over 2GB won't be accessible unless you're using a 64-bit
    operating system.

    (I think I remember one document mentioning that Windows would only be able
    to use around 3GB if 4GB was installed, but I won't swear to it.)

    The problem is that I/O devices are mapped into the same address space as
    main memory, so the addresses used by your video board, sound card, etc.
    will block access to the corresponding memory addresses.


    I don't have specific links, but you should be able to find this information
    in either Microsoft's Knowledge Base or Dell's Knowledge Base (on their web
    sites). This is also mentioned in the Owner's manual that came with my XPS
    Gen 5.

    Actually, its above the 3GB range, and only happens if you have 4GB
    installed in the box. if you put 3.5GB in there, you would see it all.

    you should see between 3.4 and 3.8 GB depending on how much the system takes
    for its own resource allocation. I have seen this vary by system,
    manufacturer, chipset installed, etc.

    A 32bit OS (2KPro, XP Pro) cant really make that much use of 4GB anyway.
    There is no way to tune it properly, as only server OS's allow for that.
    Basically, windows gives 2GB of mappable memory to itself, and then maps up
    to 2GB for each application that is running. Server OS's allow you to tune
    the memory usage so that windows will only take 1 GB, leaving 3 (phyisical)
    available for applications.

    Thanks for providing a more complete and accurate answer than mine. :)

    I was wondering about going to 4GB for my XPS 5, but after seeing that some
    of it wouldn't be accessible and Windows wouldn't make effective use of a
    lot of it, I decided it wouldn't be worth the money (for me, at least).

    I didn't keep good track of all the details once I made up my mind, since I
    don't plan on buying another computer for a few years (and by then I'll have
    to investigate a whole new set of details...).

    And this is all helpful information. As an aside, I have to wonder how many
    people actually have need of more than 1gb of RAM anyway. I feel sure that
    there are some engineering types out there who may need it, but even the
    most avid gamers I know are using 1gb with the most demanding games and
    doing fine with that.

    I'd like 2GB, but my 4550 will only go to 1GB. I do considerable work with
    digital photography, and since my camera is 12 megapixels, the images are
    very, very large.

    Tom,

    You understand that that camera spec. is completely insane, right? :) What
    are you doing? Panoramas of the Grand Canyon on the wall of your garage?

    Main reason I posted was that nobody else had mentioned the limited
    usefulness of adding memory beyond 2GB. Figured the original poster should
    at least have some sort of heads up on that.

    As far as the benefit of the memory:

    First, it may not make a major difference for most people today, but memory
    demands go up steadily. 256MB of memory was considered a large amount not
    too many years ago, but now it's not that great.

    Second, I may not need 2GB of memory and a dual-core CPU all the time. But
    when I do make use of the extra capacity, it makes a world of difference.

    On my old faithful Dim 8100, if I had a demanding, CPU-intensive task
    running in the background, it would bog the computer down and really have a
    big impact on my ability to do anything else at the same time.

    With my XPS 5, 2GB of RAM, and 3.2GHz dual-core, I can run intense tasks in
    the background and still get pretty much normal response from whatever else
    I'm using at the same time.

    During one of the recent dual-core vs. single-core threads here, as an
    experiment I decided to run two CPU-intensive applications at once.
    According to task manager I was using roughly 90% or more of the CPU for
    those two applications. Yet I barely noticed it while browsing the web,
    reading and posting in newsgroups and web forums, and doing other odds and
    ends. If I'd tried that on my single-core Dim 8100, I would have been
    screaming in frustration at all the slow downs and lagginess.

    I don't put that kind of a load on the CPU on a regular basis, but it's nice
    to know I can keep using the computer even when it's doing some very heavy
    duty work of its own in the background.

    No, the panoramas stitch together multiple 12mp images -- sometimes 8-10 of
    them.

    It's my avocation and hopefully soon my vocation.

    Oh, and I have an Epson 7600 printer that prints 24 inches by 100 feet.
    Perfect for the Grand Canyon.
